lMPROVEMENT'lN HARVESTER-DROPPERS.

Specif eationforming part of Letters PatentNo. 156,536, dated November 3, 1874;.applicatibn filed April 29, 1874.

To all whom it may concern:

Be it known that I, JAMES M. GnRIr'roN,

of Marengo, Iowa county, State of Iowa, have invented certain Improvements in Grain-Harvesters, of which the following is a specification:

the reel, and in so constructing the machine that it will either drop the grain from a dropper from the rear of the machine or deposit,

the grain in a trough at the upper end of an endless carrier, so it may be bound into bundles, the construction and operation of which,

improvements I will proceed to explain, refshowing the rear end of the dropper; Fig. 3,

a plan view on the top of the frame beneath the endless carrier, showing the main drivewheel with its accompanying gearing, and also a plan view on the top of the dropper; and Fig. 4, a vertical sectional view of the reel through the center, looking toward the outer end of the machine.

' 1n the drawings, P represents the main frame, which supports the whole superstructure ofthat end of the machine, and which is in turn supported by the main traveling drive-Wheel L, while the outer end of the machineis supported by the wheel N on the outer side of the fenderboard Z. The front of the frame P is also supported partially by means of a caster-wheel, g, to facilitate turning about easily, the shaft of which caster-wheel extends upward through the frame, with suitable leverage attached to lower or elevate the front of the machine. The platform consists of an endless apron, A, Figs. 1 and 2, which, as the machine moves forward, carries the grain forward in the direction of the arrow marked thereon between the lower end of the endless carrier 6 and the toothed roller a, as more particularly shown in Fig. 2. As the grain comes forward from the endless apron A it is caught between the toothed roller a and the lower end of the toothed carrier-belts i, which revolve on the two rollers a and carried up between the said carrier 1 and the bottoms F and B, andfinally discharged, as indicated by the arrow, on the trough 0 where it may be taken by the operator, who stands on the platform 2, Fig. 1, onto the frames 1" to be bound. The endless 1 carrier 1' operates in the frame 70, and hangs The principal features of my invention consists in the construction and arrangement of suspended at its upper end on the shaft of the roller a while at its lower end it hangs loose, so as to rise and fall to accommodate itself to any quantity of grain to be carried up. In order to prevent the straw from winding up on the roller 0 the'mctal strips facing the bottom F are bent round the said roller, as shown in Fig. 2, between the teeth, so the teeth will draw out of the grain. A similar guard, s,

is used at the upper end of the carrier 1', to prevent the teeth carrying the straw down again. Fig. 2 shows the machine arranged to carry the straw up and deposit it in the trough 0 When it is desired to cause the straw to fall on the dropper 0 the upper part of the bottom of the carrier, marked B, Fig. 2 and Fig. 1, is removed, so that the straw must fall off the upper end of the bottom F, as indicated by the arrow h, down on the dropper 0 The driver, in order to operate the dropper, keeps his foot on the upper end of the lever 0 as he rides in the seat 0 By pressing forward on the same, he causes the rear end of the dropper to be elevated enough, so the straw will not fall out, by means. of the levers 0, r, and 0 connected by cords, as shown in Fig. 2. At the same time the lever 0 presses down on the pin B of the roller D, which raises the row of circular teeth 8 up out of the way, so as to let the straw fall below on the dropper 0 When it is desired to let the straw drop off the dropper 0 the operator lifts his foot from the lever 0, which lets the rear end of the dropper fall, so the straw will slide off, and lets the teeth 8 fall down, as shown in Fig. 2, to catch what straw might fall on the dropper while it is discharging the grain. What straw has fallen on the teeth 8 while the dropper is discharging the straw is let fall on the dropper the moment the teeth are raised by the driver placing his foot on the levero again. Figs. 1 and 4 show the reel, which is supported over the platform A by the frame d. This reel consists of two belts, a running parallel with each other over the flanged pulleys s secured on the shafts 8 To the belts a are hinged,iat equal intervals, the radial arms 4, bearing the paddles a. The arms 4 are held upright and in proper position by the braces :17, which work loose in eyes on the belts and through holes in the arms as, which allows 'free play to all parts. The flanges on the pulleys prevent the belts from running off, while the cross-straps 8 cause them to each progress with the same velocity, and the bars 8 hold them the proper distance apart. By the use of a reel constructed in this manner the paddles a carry the straw along in a horizontal direction for some distance before they part from it, while there being two or more paddles in the grain at the same time lays the straw more evenly on the platform, and prevents the wind from interfering with the straw.

The reel may be raised or lowered by means of the lever e, which can be operated by the driver as he ridesin the seat, and also by the row of holes in the post m atthe rear end of the frame (1, which frame 01 is supported by the cross-pieces m and z at its outer or front end.

The motive power given to the reel is derived from the tumbling-rod m, Fig. 1, by means of the belt t from the shaft t of the gearing.

The shaft or rod m is square on eitherend, which square ends run into the knuckle-joints n n, Fig. 1, loose, so that the reel may be raised or lowered, and not interfere with the means of the propulsion. The motive power for the endless platform A and elevator or endless carrier 6 is derived from the shaft 5, Fig. 3, from the pulley 6 of which a belt runs to the pulley 8, as shown. In order to prevent a side draft, the pole g may be changed, so that it will attach to the eye 3, near the corner of the frame 5 or it may be used in the place shown in Fig.3. v

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows:

1. The combination of the belts a, pulleys s shafts s paddle arms 4, paddles a, braces av, brace-straps 8 bars 8, lever e, and tumblingrod m, all constructed, operating, and arranged substantially as and for the purposes set forth.

2. The elevator-bottom described, having the movable portion B, constructed, operating, and arranged as and for the purposes set forth.
